1. ## Functions of X

Find f(a+h) for the following function...
f (x) = 6x3
I have 6(a+h)3 but the website keeps saying it's wrong and I don't know why!

2. the 3's at the end are supposed to be cubes, so 6x^3 and 6(a+h)^3 sorry

note the use of carets to indicate an exponent.

$f(x) = 6x^3$

$f(a+h) = 6(a+h)^3$

maybe the site wants carets, or an expansion of $6(a+h)^3$

4. wells the site has a function to put in exponents, and i've tried simplifying it and its still wrong
